Cisco Firewall :: 2821 Router - Can't Configure URL Filtering Using Classic Way
Aug 16, 2012I have Zone Based Firewall running on a 2821 router and would like to configure Url Filtering with Websence . IOS running on that device is c2800nm-adverterprisek9-mz.150-1.M7.bin . Once you have ZBF config you cant configure url-filtering using classic way ( ip inspect ) and this has to be done using class , policy maps .For this to to happen it is required to have match protocol http command under the class map , it wont work using the match access-group command.[code]
Once I put match protocol http command browsing becomes dead slow , also without using match protocol command I cant continue to configure Url Filtering . Is this a problem related to IOS where match protocol command isnt working fine . I have checked CPU utlization of Router and it was roughly near 7 percent .

Cisco WAN :: 2821 - Configure Router To Use 2 ADSL Lines With Dialer And Modem In RFC2684 Mode?
Mar 9, 2011I want to configure my router to use 2 ADSL lines each with a dialer and a modem in RFC2684 mode. I have a 2821 (IOS 12.4) with an HWIC-4ESW.
My network topology is like this :
ADSL Modem 1 (RFC2684) --
(Fa0/0/0)
Router -- (Gi0/1) MyLAN
(Fa0/0/1)
ADSL Modem 2 (RFC2684) --/
1. I configure my DSL Modem in RFC 2684. The first use 172.16.0.2/29 and the second 172.16.0.3/29. I connect this devices to Fa0/0/0 and Fa0/0/1.
2. I configure Vlan1 to use the network configured on my modem :
interface Vlan1
ip address 172.16.0.1 255.255.255.248
3. I try to ping my devices :
#ping 172.16.0.2

Oct 24, 2012I have a 2821 Router with several IPSec Tunnels on it. I would like to replace this with a ASA 5510. My hope is to swap these out with minimal impact on the active Tunnels. I have the details of each Tunnel well documented. My question or concern is in configuring the Tunnels on the ASA. Do I need to configure IKE proposals in just IKEv1? If I use IKEv2, my concern is that there will be compatibility issues with the remote end of the Tunnels, or is IKEv2 functional with IKEv1? If not, then, do I just configure everything in IKEv1 and ignore IKEv2?

Apr 7, 2011We are using a 2821 Router as our boundary router. It has installed into it a 9 port HWIC for layer 2 switching as well as allowing the router to communicate on the Network Management VLAN. All of the devices on the Network Management VLAN are segregated from the managed traffic, which unfortunately also doesn't allow them external NTP services. Can the router be programmed as a NTP server so that all of the network appliances can utilize it for NTP from either it's NM Vlan IP address or from a loopback address?

Jan 19, 2010I have a Router 2821 with c2800nm-advipservicesk9-mz.124-24.T1.bin and with a Cisco Integrated Service Engine(s) Cisco Unity Express 7.1.1 in slot 1 , this router shows a high cpu utilization.I think is a bug with the IOS , because there is no voicemail configured on the CUE, there is no traffic to the CUE , just traffic from:
- voice calls
- ospf
The ospf is not the cause of the high cpu , because the high cpu utilization appears before I put the ospf proccess on the router.

View 2 Replies View RelatedCisco WAN :: Http Traffic Hanging Through 2821 Router
Mar 28, 2011I'm using a Cisco 2821 router to provide temporary Internet access for a private network of about 300 users for a conference at a hotel. The hotel has provided me a public IP address for the WAN side. On the LAN side I have a 10.x.x.x /8 subnet with the router providing DHCP and NATing (overload) across the WAN interface.
Users can pick up an IP address and access the web. Light web pages such as Google tend to load without issue, however if a user does something that takes more time, such as streaming a Youtube trailer or opening an RDP session, the connection will freeze.
It doesn't appear to be related to bandwidth availability. Pings return on average 10-15 ms. However, I will get a request time out about every 10th continual ping. Steaming video will load about 4-6 seconds worth of data, then will appear to freeze without dropping. Doing something like speedtest.net will send a large amount of data then will hang, without ever ending the conversation.
This doesn't happen when I plug a laptop directly into the hotel public Internet line. They also don't have issues with their network similar to this.
I do not have any ACLs, etc. loaded. The router is basically wide open as far as I can tell. I don't see the router resources getting used much at all.

Cisco WAN :: 2821 - Router Throughput For Ethernet WAN Connection
Apr 26, 2011I am looking to find the correct router for a 50 Mbps Ethernet connectin that is for Internet traffic. It will need to support 50 Mbps throughput, along with routing protocols for BGP, and maybe NAT/ACL's. It most likely will be a used router, in the 2800 series. I'm thinking a 2821 would work, but need to make sure before I pass it on to the customer. They currently have a 3660 they were thinking of using, but I think it would be too weak, and probably only pas 30Mbps at the most before it chokes. They are a mini ISP with their own ASN, Tier 3.

Apr 3, 2012Basically I run 3 voice gateways on 2821 routers. In two of my routers I've had fan failures, one router has had two fans die and one has had just the one.
I was going to buy the offical Cisco fan replacement kit but then I thought with such as high failure rate I'd rather buy something else and better guarentee the service to my call centres.
So, what i'm asking is:
- Is there any reason why I cannot procure a standard 80mm 12V fan with a better rating (cooling and reliability) and install this in my 2821's?
I understand this may invalidate any warranties but mine have long expired.
